The 2016 Kia Optima has been spied undergoing testing in Europe.

Since the outgoing model was one the more stylish entries in its segment, it looks like designers aren't going to mess with success. As a result, the car has a familiar shape but there appears to be longer rear doors and a lower roof. We can also see a sportier front bumper, LED-infused headlights and what appears to be a dual exhaust system.

The interior is camouflaged but features a three-spoke steering wheel, an infotainment system and plenty of chrome trim. The center stack is also angled towards the driver for easier access to commonly used controls.

Engine options will likely echo the Hyundai Sonata so expect choices to include a 2.4-liter four-cylinder engine with 185 bhp (138 kW) and 178 lb-ft (241 Nm) of torque as well as a turbocharged 2.0-liter four-cylinder that develops 245 bhp (182 kW) and 260 lb-ft (352 Nm) of torque.
